SV 258 PRO User Manual

1 INTRODUCTION
SV 258 PRO
is an outdoor monitoring system based on the
SVAN 958A
class 1 vibration and sound four-channel level
meter dedicated for ground and building vibration
applications. The portable and battery powered station can
be used for a variety of monitoring applications including
construction site monitoring, tunnelling and blasting.
The IP 67 rated case contains a lead-acid battery which
operating time can be easily extended by connecting an
external battery or a solar panel. The intelligent charging unit
allows to use a solar panel without expensive controllers and
heavy batteries.
The station case is fitted with very robust, waterproof
connectors (military standard) and comes with an IP 65
external power supply. The system uses a low-noise,
hermetically sealed tri-axial piezoelectric accelerometer
enabling the outdoor use without additional enclosures. The
accelerometers' signal ground is insulated from the mounting
surface and outer case to prevent ground loops. All
accessories fit conveniently into a second carrying case.
The monitoring station uses the mobile modem for the remote communication with the Internet.
SvanNET
,
a relay server, supports the connection between PC and the station allowing the usage of all types of SIM
cards, regardless if they have public or private IP. The use of SvanNET gives access to the status of the
monitoring
station also via mobile phone or tablet.
SV 258 PRO may be delivered with two firmware versions of SVAN 958A.
The basic firmware of SVAN 958A is dedicated for general four channel measurements and the user may
configure all channels independently. This firmware is supplied as a standard with SVAN 958A and can be
used for monitoring of vibration and sound levels when SVAN 958A is a part of the monitoring station
SC 258 PRO. This basic firmware has a so-called Ground Vibration option that allows simplified functions
for construction site monitoring.
The special firmware (SVAN 958AG) is dedicated for building vibration measurements and uses methods
based on Peak Particle Velocity and Dominant Frequency. Measurements of human vibration in buildings
are also possible as the instrument allows simultaneous measurement of velocity and acceleration of
vibrations with two independent steps of recording. In addition, it is possible to enrich the measurement with
Class 1 sound results.
Note: This manual describes SV 258 PRO comprising SVAN 958A with the basic firmware
(rev. 4.10.5).
